camera.takePicture(null, null, jpegCallback);This method captures a still image and invokes a `PictureCallback` when the image is ready. The callback can then process the image data and save it to a file or display it in the UI. The `android.hardware.Camera` package is part of the Android framework and is included in the `android.hardware` library.
